GROUT WATER-TANK MACHINE.

SPECIFICATION forming part of Letters Patent No. 604,387, dated May 24,1 898.

Application filed March 21, 1896. Serial No. 584,357. (No model.)

To all whom it may concern:

Be it known that I, FRANK E. GREGORY, a citizen of the United States,residing at Victor, in the county of Clinton and State of Michigan, haveinvented certain new and useful Improvements in Grout Water-TankMachines; and I do hereby declare that the followingis a full, clear,and exact description of the invention, which will enable others to usethe same.

A A A A are four iron or steel standards firmly braced and bolted tobeam B above. Said beam consists of two pieces of iron or steel providedwith corrugations and boltholes arranged at intervals along each piece,so that any of the corrugations in one of the pieces may be broughtopposite one of the corrugations in the other piece, the matingcorrugations forming a bearing for the upper end of upright shaft 0. Bythis means the length of the beam B may be varied and the apparatusaccommodated to tanks of different diameters. The bolt-holes are soplaced as to be in register for all adjustments of the beam.

Shaft O enters beam 13 B at its top and rests upon block M, which restsupon the ground. The arms D D. are fastened by grips N N to the shaft 0.The lower arm D is to shape the bottom of the tank and holds the insideshaper E bolted thereto with a loose joint to allow the top of saidshapers to be moved to and from the sides of the tank as it is beingconstructed by means of lever H. The shapers are concaved plates,between which the grout is shaped to form the wallof the tank. The upperarm D passes over the top of the shapers and curves down to the bottomof the outside shaper F, where it is bolted with a loose joint to allowsaid shaper to be moved to and from the tank by means of said lever H.

To one side of upper arm D is bolted a plate G, to the center of whichis pivoted lever H, and to the other side ofupper arm D is bolted thegage-plate J, provided with notches on its upper edge, as shown, whichengage lever H and hold it in the required set position. Lever H isconnected with shapers E F by rods I L'as shown.

The position of the shapersmay be changed by placing the leverI-I in'difierent notches, and such changes of position vary the thickness ofthe wall of the tank toward and at the top, while the bottom is notvaried, being held stationary by the arms D D.

The trough K, constructed of iron or steel, is loosely attached by rodsL L to the shapers and receives the grout used in the construction ofthe tank, which passes therefrom between the shapers E and F and rises,as the walls of the tank are built, to the lower edge of the upper armD, which forms the top of the tank. Said "rods L L are fastened to edgeof-shapers E and F.

The upright or lower part of trough K is placed loosely between rods LLand edge of shapers E and F to hold trough Kin position and admit of itsbeing raised as wall is built, bottom of trough K resting on top ofwall.

To operate said machine in the formation of a tank, first adjust andlevel the beam and plumb the shaft, the standards being staked down tohold the machine in place. Then the arms and shapers are to be adjustedto form the desired sized tank. A layer of grout is first placed Wherethe tank is desired, and the bottom is formed by revolving the lower armD over the surface of the grout sufficient to level it after it has beenthoroughly packed. To form the wall of the tank, set the lever ingage-notch to make the thickness of the top of tank required. Then putgrout down, trough, packing solid between shapers and upright part oftrough, turning lever to throw shapers from the sides of the tank, and,taking hold of upper arm, turn shapers toward the trough within about aninch of their width. Repeat this process around'the tank until built torequired height. Then adjust the arms and shapers to allow a coat ofcement being put upon the tank already formed for the combination ofstandards A, adjustable cross-beam B, vertical shaft 0 having its upperend journaled therein and its lower end supported, horizontal arms Dsecured to the 10 shaft 0, shapers E and F secured at their lower endsto the free ends of the arms D and their upper ends adjustablycontrolled substantially as described.
